Abstract: 680,715. Gloves. DUNLOP RUBBER CO., Ltd., and CROMPTON, L. April 11, 1950 [April 21, 1949], No. 10548/49. Class 141. [Also in Group VIII] Clothing affording protection against X-rays comprises one or more layers of lead glass fabric and one or more layers adherent thereto of rubber or a synthetic resin composition in which may be dispersed a material comprising an element of high atomic number such as lead powder or a compound of lead or barium (see Group VIII). A glove or gauntlet may be produced by stretching a stockinette lining over a former, covering with rubber by one or more dips into a latex (or rubber) composition containing vulcanising ingredients, each layer being allowed to cool before the next dip, applying a shaped layer of lead glass fabric, and applying a further coating of latex composition by dipping: one or more layers of the glass fabric with intermediate layers of the latex may be thus applied, a final dip in the latex composition is given, and the whole assembly vulcanised by heating. Alternatively, a preformed composite material having a layer of lead glass fabric and a layer of rubber adherent thereto is cut into pieces of appropriate shape which are sewn together in pairs to form gloves and the seams and stitches covered with a tape of a lead glass fabric proofed with rubber composition which is bonded to the glove as by means of rubber adhesive cement.

Title: An interior grinding machine for grinding out bores accurately
IPC: B24B5/06
Filed: 1929-04-05
Abstract: 323,694. Jung, K. April 5, 1929. Turning.- In an internal grinding machine, wherein the grinding-wheel is trued prior to taking the finishing cut on the work, the work and a trueing diamond, or other tool are mounted on a rotatable head so that the work can be moved from the grinding-wheel, and the diamond brought into position to operate on the grinding-tool. The machine consists of a bed 1 upon which the grinding-wheel 5, driven by an electric motor 7, is movable by longitudinal and cross slides 2, 3. The work is carried by a chuck 14 carried by a spindle 13 in a head 12 rotatably mounted in a fixed part 11, the spindle having thereon a pulley 15 driven by a belt 16 passing over guide pulleys 17, 18, and the head also carries an idle pulley 15a, so that on rotation of the head through 180‹ in the part 11, the pulley 15 moves away from the belt 16 and the idle pulley 15a is driven. This rotation of the head 12 brings a diamond &c. tool 23, mounted on guides 20, 21 on the head, into position to true the grinding-wheel, the slide 2 being traversed for that purpose. A reverse rotation of the head restores the work to the working position wherein the finishing cut is taken with the trued grinding-wheel. The head may be rotated by hydraulic means, this consisting of a piston 28 movable in a cylinder 29 fed, through valves and inlets 30, 31 with fluid. The piston is formed on one side as a rack, which, through gearing 27, 25, 24, serves to rotate the head 11.

Title: Improvements in or relating to looms for weaving
IPC: D03D29/00

Abstract: 658,273. Hand looms; shedding motions CRAYMER, H. J. April 20,.1948, Nos. 10825 and 25564. [Classes 142(i), 142(ii) and 142(iii)] A shed is formed, in a hand loom, by fork-like members engaging one set of warp threads and a bar engaging a second set of warp threads. The tines of the forklike members are of sufficient length to retain the warp threads between them during shedding. The .. second set of warp threads may also be moved by fork-like members. The invention may be applied to power looms. A carriage 23 carrying a warp beam supplying threads a and carrying fork-like members 29, has. mounted upon it a carriage 32 carrying a warp beam supplying threads b. Threads a and b pass down opposite sides of a V-. shaped trough 6 through which a shuttle passes and the fabric c moves downwards over a roller 37 and is taken up on a roll 41. Operation of a pedal 12 swings a lever 15 about a pivot 16 and a roller 17a engageing a groove in a member 18 turns a lever 19 about its pivot 19a. Movement of the lever 19 and of a lever 34 secured to the pivot 16 causes the carriage 23 to move to the right and carriage 32 to move to the left to change the shed. A link 20, which is moved when the lever 19 is turned, lowers arms 9, 10 so that the trough 6 and a reed 45 are lowered to beat-up the weft. A ratchet 42 on the lever 9 operates the take-up mechanism. The shuttle is provided with wheels and the weft issues from an opening in the underside of the shuttle. The wheels assist in laying the weft in the fell. The fork-like members 29 may comprise a shank portion 49, a pair of parallel blades 50 and parallel tails 51 and may be made of wood, wire, metal or of a moulded material. In an alternative contruction, Fig. 8, warp beams 55, 58 remains stationary and the threads a and b pass over stationary guides 56, 59 positioned so that no extra tension is placed on the threads during shedding.

Abstract: 254,662. Toyoda, K. April 24, 1926. Shuttle-changing mechanism.-The front and back plates 19, 20 of the shuttle box of an automatic shuttle-changing loom are mounted on a common rocker-arm 18, the front portion of the plate 19 having a cam-face 22. A shuttle guideplate 23 is pivoted on the lay and is normally in an inclined position under the action of a spring 27. When the weft is exhausted or broken, an arm 13 is raised and in turn raises a bunter arm 9 into the path of a lug 11 on the lay. As the lay beats up, the arm 9 is forced forward to rock arms 8, 6 on a shaft 7 and push forward a pusher rod 3. The rod 3 advances the lowest shuttle in the magazine 2 between the cam-face 22 and the plate 23, which are forced apart to a horizontal position against spring action. The front and back plates are thereby raised to allow shuttle S<1> to enter the box and force out the used shuttle S on to a receiving plate 30 carried by the back plate 20 and against a stop 31 on the lay. The plates 19, 20 then return to normal position, and the shuttle S is discharged.

In a vessel having a cargo-hold for mud or similar water-bearing materials, the hold is subdivided by at least one partition having an opening at the bottom of the partition such that on supplying mud to one part of the hold it will flow gradually through the opening into another part of the hold along the floor of the vessel, and at least the latter part of the hold separated by this partition is provided with an overflow drain for the water in the upper part of the vessel. The hold is divided by a partition 6 and subdivided by partitions 7 and 8, each partition having an opening in its lower part which can be closed by valves 9, 11, and 12 respectively. Normally the hold is full of water up to the water level 16. Mud put into the compartment 13 enters the bottom of compartments 17 and 14, and from the latter to compartment 18, as shown at 19 and 20. The water level in compartments 17 and 18 rises and flows out of drains 21, slidevalves 22 being provided to govern the level at which the water flows out. Hinge-valves 23 at the top of partitions 7 and 8 allow water to flow from compartments 13 and 14 into compartments 17 and 18 respectively. In another embodiment a suction-hopper is shown having one partition only which divides the hold into a loading section at one end and a larger section into which mud flows and displaces the water over the drain.
